Detailed Description
The present invention will be further explained with reference to the drawings (hereinafter, the right side direction of fig. 1 is referred to as the front).
An automatic car arrester installed in a cage comprises a rear car arrester 3 and a front car arrester 4, wherein the rear car arrester comprises a rear car arrester bottom plate 31, a rear car arrester 32 and a rear car arrester support 33, the rear car arrester bottom plate 31 is fixed on the bottom surface of the cage 1, the rear car arrester support 33 is fixed on the rear car arrester bottom plate 31, the rear car arrester 32 is positioned on the rear car arrester support 33 and can rotate relative to the rear car arrester support 33, and the rotating surface is basically parallel to the direction of a mine car 2 entering and exiting the cage 1; the top end of the rear car stopping claw 32 is higher than the axle height of the mine car without the action of external force; the gravity center of the rear car stopping claw 32 is positioned at one side of a rotating shaft between the rear car stopping claw 32 and the rear car stopping claw support 33, which is close to the nearest cage door, and the side of the rear car stopping claw 32 where the gravity center is positioned is provided with a touch block, and the touch block touches the rear car stopping device bottom plate 31 under the action of no external force, so that the top end of the rear car stopping claw 32 cannot rotate to the side where the gravity center is positioned;
in fact, for the sake of simplicity, the rear arrester 32 can be made triangular, or substantially triangular, so that its centre of gravity is located on the side of the pivot adjacent to the nearest cage door, and its bottom corner on the side of the centre of gravity acts as an abutment. Thus, when the mine car 2 enters the cage 1, the axle of the mine car pushes the top end of the rear car stopping claw 32 to rotate towards the side opposite to the side where the center of gravity is located, and at the moment, the rear car stopping claw 32 does not block the mine car from entering the cage 1;
the front car arrester 4 comprises a front car arrester support 41, a front car arrester 42, a pull rod 43, a pull rod support 44 and a front car arrester bottom plate 45;
the front car stopping claw support 41 and the front car stopping claw 42 have the same structure as the rear car stopping support 33 and the rear car stopping claw 32, but the gravity center side of the front car stopping claw 42 is opposite to the gravity center side of the rear car stopping claw 32;
the pull rod 43 is hinged with one end, far away from the front car stopping claw support 41, of the bottom of the gravity center side of the front car stopping claw 42, or only the pull rod 43 is hinged with the part of the side, where the gravity center of the front car stopping claw 42 is located, of the bottom of the front car stopping claw 42, the front car stopping claw support 41 and the pull rod support 44 are both fixed on a front car stopper base plate 45, and the middle of the pull rod 43 is hinged with the pull rod support 44, so that when the free end of the pull rod 43 moves downwards, the top end of the front car stopping claw 42 can be driven to rotate to the longitudinal position, which is lower than the height.
The front car stopping claw 42 may also be triangular, so that the center of gravity thereof is located on the side of the rotating shaft close to the nearest cage door, and the bottom corner thereof located on the side of the center of gravity serves as a contact block. When the mine car is going to come out of the cage 1, the external cradle presses down the spare end of the pull rod 43 to drive the front car stopping claw 42 to rotate to the height that the top end is lower than the axle of the mine car, so that the mine car can come out without hindrance. When the cradle does not press the free end of the pull rod 43, the front catcher 42 is higher than the axle of the car, and together with the rear catcher 32, it limits the position of the car in the cage 1.
The spacing between the front catcher 42 and the top of the rear catcher 32 is slightly greater than the distance between the axles of the car, and this difference is no greater than 20 cm. The difference undersize, the mine car gets into cage 1 and is restricted, and the difference is too big, and the mine car 2 rocks the range increase in cage 1. Of course, this difference is directly related to the height of the car stopping pawl, the difference in height between the top of the pawl and the top of the axle, and the angle of rotation of the pawl as the car 2 enters and exits the cage 1. The height of the top points of the two car stopping claws, the distance between the two car stopping claws and the distance between axles of the mine car can be obtained through simple limited tests, if the height of the car stopping claws and the height of the axles are determined, the distance between the front car stopping claw and the rear car stopping claw can be adjusted, and similarly, two parameters are determined firstly, then the remaining parameter is adjusted, and a satisfactory result can be always obtained.
The working process in actual use is as follows: (for ease of understanding, the following descriptions of up, down, left, right, clockwise, and counterclockwise are given with respect to the components in the drawings, up, down, left, right, clockwise, and counterclockwise)
When no mine car 2 enters the cage 1 and the cage 1 is in a ready state, the two car stopping claws are in a car stopping state;
when the cage 1 is in place and the mine car 2 enters the cage 1, the front wheel shaft of the mine car 2 firstly impacts the rear car stopping claw 32, the rear car stopping claw 32 is forced to rotate clockwise to be opened, and at the moment, the mine car 2 can enter the cage 1 through the rear car stopper 3. After the mine car 2 all gets into in the cage 1, the left weight of back car stopping claw 32 pivot is greater than the weight on right side, under the effect of gravity, back car stopping claw 32 anticlockwise rotation resumes the state of holding up the car, the cradle rises the back, front and back car arrester all is in the state of holding up the car, mine car 2 is fixed in cage 1, cage 1 can promote the operation, when cage 1 moves from top to bottom in the pit shaft, the car arresting claw of front and back car arrester fixes mine car 2 in cage 1, prevent that the sports car accident from appearing in mine car 2.
When the cage 1 runs to a required position and the mine car 2 needs to leave the cage 1, the cradle falls down, pressure is applied to the tail end of the pull rod 43, the front car stopping claw 42 is driven to rotate anticlockwise, the front car stopper 4 is in a car passing state, and the mine car 2 leaves the cage 1 through the front car stopper 4 as shown in fig. 6. When the cradle is lifted, because the centers of gravity of the pull rod 43 and the front car stopping claw 42 are both positioned between the two supports, the front car stopping claw 42 rotates clockwise to reset under the action of gravity, and the car stopping state is recovered, and at the moment, as shown in fig. 5, the two car stoppers in the cage 1 are both recovered to the car stopping state and enter the next cycle.
The front car arrester always keeps the gravity center of the front car arresting claw 42 and the gravity center of the pull rod 43 between the two rotating shafts so as to finish the action of automatically resetting and arresting the car, and when the front car arrester is started, the front car arresting claw 42 is rotated by the pressure of the cradle to discharge the mine car; the rear car arrester 3 always keeps the gravity center at the rear side of the rotating shaft in the process that the mine car 2 passes through by means of the structural characteristics of the rear car arrester 32, and the mine car 2 passes through and completes the automatic resetting car arrester action by means of gravity.
The utility model discloses not confine to above embodiment, it is different when the play car direction of well head shaft bottom cage, can change into two preceding car stoppers of symmetry installation around the cage. When the number of the tramcars in the cage is multiple, two car stoppers can be respectively installed on the outer sides of the first tramcar and the last tramcar.
